Sorry to say this, but I'm glad to see this post. I have a 36 Sovran with 450c's and ZF transmissions. We just finished our second season with it and I started noticing early this season that I have a whine at low rpm's. It's more noticeable around the harbor, for example, with the quieter surroundings. I've lifted the day hatch to the engine room and the trannies are right there and I can't hear anything that makes me nervous. I changed the oil (straight 30w) when we bought it and check it regularly, and it's still perfectly clear. Let us know if you learn more!
